Step-by-step explanation:

You can start by representing the speed of the water as x and the speed of the dolphin as y, and writing an equation.

y+x=50

y-x=30

Adding these two equations together, you get:

2y=80

y=40 for the speed of the dolphin in still water. Now, you an use one of the previous equations to find the speed of the current.

40-x=30

x=10

Answer:

Step-by-step explanation:

If two quantities are inversely proportional, it means that an increase in the value of one variable would cause a corresponding decrease in the other variable and vice versa.

Given that M varies inversely as the square of P, if we introduce a constant of proportionality, k, the expression becomes

M = k/P²

If M = 9 when P = 2, then

9 = k/2² = k/4

k = 9 × 4 = 36

Therefore, the inverse variation equation is

M = 36/P²

When P = 3,

M = 36/3² = 36/9

M = 4

Given:

Given that AGN is a triangle with circle inscribed in it.

The circle touch the triangle at the point R, T and E.

The length of AR is 35 units.

The length of RG is 21 units.

The length of NE is 19 units.

We need to determine the perimeter of the triangle AGN.

Length of GE:

Since, we know the property that, "if two segments from a exterior point are tangent to the circle, then they are congruent".

Since, RG and EG from an exterior point G are tangents to the circle, then RG and EG are congruent.

Thus, we have;

[tex]RG=EG[/tex]

 [tex]21=EG[/tex]

Thus, the length of GE is 21 units.

Length of TN:

Since, we know the property that, "if two segments from a exterior point are tangent to the circle, then they are congruent".

Since, TN and NE from an exterior point N are tangents to the circle, then TN and NE are congruent.

Thus, we have;

[tex]TN=NE[/tex]

[tex]TN=19[/tex]

Thus, the length of TN is 19 units.

Length of AT:

Since, we know the property that, "if two segments from a exterior point are tangent to the circle, then they are congruent".

Since, AT and AR from an exterior point A are tangents to the circle, then AT and AR are congruent.

Thus, we have;

[tex]AT=AR[/tex]

[tex]AT=35[/tex]

Thus, the length of AT is 35 units.

Perimeter of AGN:

The perimeter of AGN is given by

[tex]\triangle AGN=AR+RG+GE+EN+TN+AT[/tex]

Substituting the values, we get;

[tex]\triangle AGN=35+21+21+19+19+35[/tex]

[tex]\triangle AGN=150[/tex]

Thus, the perimeter of the triangle AGN is 150 units.

Answer:

150

Step-by-step explanation:

Segment AE divides the triangle into two congruent right angle triangles

AG = AN = 35 + 21 = 56

NG = 2(19) = 38

Perimeter = 56 + 56 + 38

Answer: The wheels turn about 3771 times in 5 miles.

Step-by-step explanation:

Given, Kelly rides on her bicycle such that the number of times wheels turn for every 140 feet = 20

Turns for every feet = [tex]\dfrac{20}{140}=\dfrac{1}{7}[/tex] ...(i)

To find : Number of times wheels turn in 5 miles.

Since , 1 mile = 5,280 feet

Then, 5 miles = 5 x (5,280 feet) = 26,400 feet

Now , Number of times the wheels turn in 26,400 feet = 26400 x (Turns for every feet)

[tex]26400\times\dfrac{1}{7}=3771.42857143\approx3771[/tex]   [From (i)

Hence, the wheels turn about 3771 times in 5 miles.

Answer:

in scientific notation​ the answer is 5.75x10^8

Answer: [tex]5.75[/tex] [tex]x[/tex] [tex]10^{8}[/tex]

Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.

So here, we have 5.75000000 and notice that there

is only one digit to the left of the decimal point.

Next, we count the number of places the decimal point would

need to move to get back to the original number, 575,000,000.

Since we would need to move the decimal point 8 places to the right,

we have an exponent of positive 8.

Now, scientific notation is always expressed as a number between 1 and 10 including 1 but not 10 and it is multiplied by 10 to a certain power that must be an integer.

So we have [tex]5.75000000[/tex] [tex]x[/tex] [tex]10^{8}[/tex].

Notice that the exponent is positive.

This is because we would need to move the decimal point to the right in order to get back to the original number.

So 575,000,000 can be written in scientific notation

as [tex]5.75000000[/tex] [tex]x[/tex] [tex]10^{8}[/tex] or just [tex]5.75[/tex] [tex]x[/tex] [tex]10^{8}[/tex].

Remember that we can drop zeroes at the end of a decimal.

So we have [tex]5.75[/tex] [tex]x[/tex] [tex]10^{8}[/tex].

Answer:

x = 51.1 degrees

Step-by-step explanation:

We notice that we can use the sine formula.

Why?

Well because Sin x =  (opposite side) /  hypotenuse

sin x = 7/9

x = arcsin 7/9 = 51.05755 degrees

rounded to the nearest tenth.

x = 51.1 degrees

The most vital factor for classifying two species into the same group is if they evolved from a shared ancestor, reflecting their place in the same clade and genetic similarities.

The most important factor for classifying two species into the same group is their evolutionary history, specifically whether they evolved from a shared ancestor. When scientists classify species, they adhere to the fundamental principle that all members of a group, or "clade," must have a recent common ancestor that is not shared with species from other groups. This is based on the idea that species within the same group will share more genetic similarities and phylogenetic traits than with those from different groups due to their more recent common ancestry.

Option A might seem plausible, as species in a group often share similar traits, but shared traits alone are not enough for classification without evolutionary context. Option C is incorrect because common names do not reflect scientific classification. Option D is also incorrect as geographic location is not a determinant for taxonomic classification. Thus, the correct answer to the original question is B, "The species have different common ancestors," as having a recent common ancestor is the most critical criterion for grouping species together.

Given:

It is given that the value of the graph when the input 7 is [tex]g(x)=4[/tex]

We need to determine the value of x when [tex]g(x)=4[/tex]

Value of x when [tex]g(x)=4[/tex]:

The value of x can be determined by using the graph.

From the graph, we need to determine the value of x when [tex]g(x)=4[/tex] other than the value x = 7.

This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.

Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.

Therefore, the input value is x = -8 which makes [tex]g(x)=4[/tex]

Hence, the input value other than 7 for which [tex]g(x)=4[/tex] is x = -8.

The input value other than 7 for which g(x) = 4 is x = -8.

It is given that the value of the graph when the input 7 is g(x)=4

We need to determine the value of x when g(x)=4

Value of x when g(x)=4:

The value of x can be determined by using the graph.

This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.

From the graph, we get that the graph of g(x) passes through the point (x = -8, y = 4),

Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.

Then indeed, the input value (x) other than 7 for which g(x) = 4 is x = -8.

As, the function g(x) takes the value of 4 at x = -8, according to the graph.

Therefore, the input value is x = -8 which makes g(x) = 4.

Hence, the input value other than 7 for which g(x) = 4 is x = -8.

Answer:

105 sqrt(2) =x

Step-by-step explanation:

Since this is a right triangle we can use trig functions

so  sin theta = opposite side/hypotenuse

    sin 45 = x/210

Multiply each side by 210

210 sin 45 = x

We know sin 45 = sqrt(2)/2

210 * sqrt(2)/2 = x

105 sqrt(2) =x

Answer:

B

Step-by-step explanation:

Using trig ratios

sin(45) = opposite/hypotenuse

sin(45) = x/210

sqrt(2)/2 = x/210

x = 210sqrt(2)/2

x = 105sqrt(2)

you should get 54

then divide by 18

you get three

You can make 3 necklaces from 137.16 centimeters of silver chain, given that each necklace is 18 inches long. We first converted the necklace length to centimeters, and then divided the total length of silver chain by the length of each necklace.

To find out how many necklaces can be made from 137.16 centimeters of silver chain, we first need to convert the units because the length of the necklace chain is given in inches, while the total amount of silver chain is given in centimeters.

We know that 1 inch is equal to 2.54 centimeters. Therefore, if each necklace is 18 inches long, the length of each necklace in centimeters is 18 inches * 2.54 cm/inch = 45.72 cm.

Now, to find the number of necklaces that can be made, we divide the total length of silver chain by the length of each necklace. That is 137.16 cm / 45.72 cm/necklace = 3 necklaces (rounded down to the nearest whole necklace, because we cannot make a fraction of a necklace).

sin ( θ ) = 3√21 / 17

Step-by-step explanation:

                               cos ( θ ) = 10 / 17

Find:-

- Find sin ( θ ) :

Solution:-

- We will draw a right angle triangle in the first quadrant. With base, B = 10 and hypotenuse H = 17. Since,

                               cos ( θ ) = B / H = 10 / 17

- Using pythagorean theorem determine the perpendicular side length:

                               H^2 - B^2 = P^2

                               17^2 - 10^2 = P^2

                               √189 = P

                              P = 3√21

- Now evaluate sin ( θ ):

                               sin ( θ ) = P / H

                               sin ( θ ) = 3√21 / 17

12y=$3

114 cans

Step-by-step explanation:

Let the cost of every can be represented by y. Therefore, for 12 cans, the cost will be the product of y cans and 12 hence cost is 12y

Since the cost incurred is $3 then we can represent these as

12y=$3

To solve for y, we divide both sides by 12 hence

Y=$3/12=$0.25

To find the number of cans that one will get with a buget of $28.5, we divide the budget by the cost of a can. This will be $28.5/$0.25=114 cans

Proved down

Step-by-step explanation:

To prove that a triangle is isosceles use the distance formula to find the length of its side and check if there are two sides equal.

To prove that a triangle is right find the square of the longest side and then find the sum of the squares of the other two sides, if the two answers are equal, then the triangle is right (converse of Pythagoras Theorem).

The formula of the distance between two points is:

[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]

∵ x = (-1 , 5) and y = (4 , 4)

∴ [tex]x_{1}[/tex] = -1 and [tex]x_{2}[/tex] = 4

∴ [tex]y_{1}[/tex] = 5 and [tex]y_{2}[/tex] = 4

- Substitute them in the formula of the distance to find xy

∵ [tex]xy=\sqrt{(4--1)^{2}+(4-5)^{2}}=\sqrt{25+1}[/tex]

∴ [tex]xy=\sqrt{26}[/tex]



∵ x = (-1 , 5) and z = (-2 , 0)

∴ [tex]x_{1}[/tex] = -1 and [tex]x_{2}[/tex] = -2

∴ [tex]y_{1}[/tex] = 5 and [tex]y_{2}[/tex] = 0

- Substitute them in the formula of the distance to find xz

∵ [tex]xz=\sqrt{(-2--1)^{2}+(0-5)^{2}}=\sqrt{1+25}[/tex]

∴ [tex]xz=\sqrt{26}[/tex]

∵ xy = xz

- The isosceles triangle has two equal sides

∴ Δ xyz is an isosceles triangle

∵ y = (4 , 4) and z = (-2 , 0)

∴ [tex]x_{1}[/tex] = 4 and [tex]x_{2}[/tex] = -2

∴ [tex]y_{1}[/tex] = 4 and [tex]y_{2}[/tex] = 0

- Substitute them in the formula of the distance to find yz

∵ [tex]yz=\sqrt{(-2-4)^{2}+(0-4)^{2}}=\sqrt{36+16}[/tex]

∴ [tex]yz=\sqrt{52}[/tex]

yz is the longest side lets find its square

∵ (yz)² = ([tex]\sqrt{52}[/tex] )²

∴ (yz)² = 52

- Lets find the sum of the squares of the other two sides

∵ (xy)² + (xz)² =  ([tex]\sqrt{26}[/tex] )² +  ([tex]\sqrt{26}[/tex] )²

∴ (xy)² + (xz)² = 26 + 26 = 52

∴ (yz)² = (xy)² + (xz)²

- That means the angle opposite to yz is a right angle

∴ Δ xyz is a right isosceles triangle
